This paper isolates the role of conflict or disagreement on inflation in two ways. In the first part of the paper, we present a stylized model, kept purposefully away from traditional macro models. Inflation arises despite the complete absence of money, credit, interest rates, production, and...

This paper studies how household inequality shapes the effects of the zero lower bound (ZLB) on nominal interest rates on aggregate dynamics. To do so, we consider a heterogeneous agent New Keynesian (HANK) model with an occasionally binding ZLB and solve for its fully non-linear stochastic...

The US and other advanced countries suffered bursts of severe inflation in 2021 and the first half of 2022, followed by declines of inflation later in 2022, in some countries. In times of high volatility of price determinants--cost and productivity--inflation can jump upward and fall downward at...

We develop a multisector, open economy, New Keynesian framework to evaluate how potentially binding capacity constraints, and shocks to them, shape inflation. We show that binding constraints for domestic and foreign producers shift domestic and import price Phillips Curves up, similar to...

This paper proposes a non-linear New Keynesian Phillips curve (Inv-L NK Phillips Curve) to explain the surge of inflation in the 2020s. Economic slack is measured as firms' job vacancies over the number of unemployed workers. After showing empirical evidence of statistically significant...

This paper provides new evidence on a long-standing question asked by Shiller (1997): Why do we dislike inflation? I conducted two surveys on representative samples of the US population to elicit people's perceptions about the impacts of inflation and their reactions to it. The predominant...

We study how monetary policy affects subcomponents of the Personal Consumption Expenditures Price Index (PCEPI) using local projections. Following a monetary policy contraction, the response of aggregate PCEPI turns significantly negative after over three years. There are stark differences in...

We study a model where households make decisions according to a dual-process framework widely used in cognitive psychology. System 1 uses effortless heuristics but is susceptible to biases and errors. System 2 uses mental effort to make more accurate decisions. Through their pricing behavior,...

We show that firms' nominal required returns to capital (i.e., their discount rates) are sticky with respect to expected inflation. Such nominally sticky discount rates imply that increases in expected inflation directly lower firms' real discount rates and thereby raise real investment. We...

This paper derives the curvature properties of the short-run Phillips curve in a class of canonical models of price-setting frictions. Contrary to conventional thinking, the Phillips curve is asymptotically horizontal for high levels of economic activity and asymptotically vertical for low...
